Sorry for asking this here, I figured 2013 2.0T A6 is almost the same as B8 (engine, tranny, and brakes -wise) plus I will have higher chances of someone actually answering the question.
For the past few weeks I've been experiencing very strange vibration while braking/stopping on uneven surfaces. When coming to a complete stop on good pavement, car brakes fine. Vibration is transferred through a brake pedal.
I am obviously suspecting brake components, although took calipers off and there is still meat left on the pads and brake rotors surface "seem" fine.

Thank you
